[1]} and [2]} used both optimal estimation and full-state information control to derive optimal sensor and actuator placement for the complex linearized Ginzburg-Landau system and a low Reynolds number cylinder wake, respectively. [3]} also employed resolvent-based analyses to discover the optimal forcing variable and location for an actuator aiming at preventing airfoil flow separation. [4]} leverage resolvent analyses to assess the potential of opposition control for drag reduction and turbulence control.
